By a dual approach we establish sufficientconditions for existence and multiplicity of solutions for this problem.doi:10.48550/arXiv.1603.01193Santos, Carlos AlbertoZhou, JiazhengC. A. Santos, J. Zhou; Infinite many blow-up solutions for a Schro¨dinger quasilinear elliptic problem with a non-...
Infinite series are useful forfinding approximate solutionswhen a problem can’t be expressed in terms of a knownfunction, or where there isn’t aclosed-formor exact solution. For example, manydifferential equationsdon’t have solutions of known functions orelementary functions; Those solutions can ...
The definition is the obvious extension of the definition of a finite-order jet, so that two maps are ∞-equivalent when they are k-equivalent for each k. Definition 2.2 If f, g : M→ N are C∞ maps between C∞ manifolds then they are ∞-equivalent at x∈ M if f(x) = g(x)...

An infinite sequence is a sequence of numbers that does not have an ending. Explore the definition and examples of infinite sequence and learn...
Therefore, the determination of the pre-exponential factor of Henry's constant is needed while using this definition, and the well-known methods proposed by Adamson [151] or by Hobson [152], or by Park and Donnet [70] could be considered for this purpose: 1. According to Adamson and Lin...
Definition 16Let and be arbitrary subsets of generalized points and \(k\in \mathbb {N}\cup \{+\infty \}\). Then we say that $$\begin{aligned} f:X\longrightarrow Y\text { is a generalized }{\mathcal {C}}^{k}\text { function } \end{aligned}$$...
While it is usually the case that a solution is found, it is also possible to have more than one solution, which is infinitely many. In other cases, no solutions can be found at all because of the nature of the expressions involved....
Definition VIII.2 Let ε≠ 0. Then we define x≈y(ε) if and only if xε≈yε. Relative approximate equality has the same properties as approximate equality. In particular, all properties stated above are true when ‘≈’ is replaced by ‘≈ (ε)’. We shall occasionally...
Complete the definition. A set is countable if the set isDefine subsets and give a relevant example along with it.Answer the following questions about the given sets. a. Are the sets equivalent? Explain. b. Are the sets equal? Explain....
